Discord automatically shows your friends the games you’re playing. If a game uses Discord’s Rich Presence feature, your friends can even see where you are in the game. This is how you can disable this feature and increase your privacy while playing the game.
Open the Settings menu in Discord by clicking the gear in the bottom left next to your name and avatar.
Go to the “Activity Privacy” tab on the left. Turn off the “Show current activity as a status message” option and Discord will stop sharing your gaming activity.
You can now close the Settings screen.
You can always enable this setting again by following these same steps if you want Discord to show others what you’re playing, metadata about your game status, or even what you’re listening to on Spotify.
